Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is characterized in that the lubricating head is arranged on an arm or a holding body, and the arm or the holding body pushes out the lubricating head by a swinging movement or a radial movement using a swinging drive device or a moving drive device. A metal strand of the type adapted to be moved into and away from a position coaxial with respect to the axis and provided with means for creating a relative interlock between the lubricating head and the tool to be lubricated; or) a device for lubricating tools in direct or indirect extruders for pipes.

Conventionally, tools are commonly used, such as metal strands extruded into the Nada fort Yun Yun valve register and the tuna striped tuna chicks, the Nada crocodile mausoleum foot groove.

In this case, the worker performing the coating work is generally on one side of the extruder, and it is extremely difficult to coat the opposite side of the extrusion mandrel. Uneven distribution of lubricant. The lubricating tool consists of a rod wrapped with a piece of cloth;
The rod is dipped in liquid lubricant and applied to the extrusion tool by hand. In this case, the dripping lubricant will seriously stain the machine and its surroundings. It costs more. In addition, tools contaminated by spilled lubricant must be manually wiped clean. It is therefore an object of the present invention to provide a lubrication device for the tools of a direct or indirect extruder for metal strands and/or tubes, which obviates the aforementioned drawbacks, i.e. enables uniform lubricant application without labor costs. The objective is to significantly limit or eliminate contamination.

To achieve this objective, the invention provides a lubrication head in which a holder is provided which receives a candle-shaped solid lubricant which melts on contact with a hot tool. Such a device allows automatic lubrication of the tool, and lubrication can take place during the extrusion cycle.

Uniform lubrication. In some cases, drops of lubricant melted by the hot tool during lubrication are collected and recycled. In an embodiment of the invention, for automatic lubrication of a circular extrusion plate mounted on the extrusion ram in a metal strand direct extruder or a closing piece arranged in a movable beam in a metal strand indirect extrusion machine, the extrusion axis The arm, which can be rotated toward the A receiving device for the lubricant is provided for rotationally pressing the lubricant against the end face of the lubricant, the diameter of the lubricant being larger than the diameter of the extrusion plate or closing piece.

Automatic lubrication of the end faces of the manual push-out plate or closure piece thus takes place.

Since the lubricant has a larger diameter than the ejector plate or closure piece, the lubricant is rotated and crimped using a drive motor movable in the track direction on the swivel arm, while the immovable ejector plate or closure piece The edges of the pieces are also coated with lubricant. In this case, the axial movement of the drive motor takes place pneumatically or hydraulically. In another embodiment of the invention, an arm pivotable towards the extrusion axis is arranged at its free end in a receiving device for automatic phantom control of a rectangular extrusion plate mounted on an extrusion ram. A rectangular lubricant is held movable in the extrusion axis direction by a pneumatic or hydraulic mechanism (cylinder) in order to press against the rectangular extrusion plate.

As a result, the extrusion plates are automatically and satisfactorily lubricated even in extrusion blocks having a square cross section and requiring rectangular extrusion plates.

This is because when the lubricant is applied to the extrusion plate, it easily melts due to the heat of the extrusion plate, forming a suitable lubricant film on the extrusion plate. In a further embodiment of the invention, for the lubrication of a rectangular extrusion plate mounted on the extrusion ram, an arm pivotable towards the extrusion axis is provided at its free end. the arm holds at its free end a drive motor via a guide mechanism extending in the direction of the extrusion axis and a guide mechanism extending transversely to the extrusion axis; A circular lubricant is received within the device.

Advantageously, the guide mechanism extending transversely to the extrusion axis comprises a guide extending transversely to the extrusion track line and a slide movable in this guide by a hydraulic or pneumatic power mechanism. A guide is located at the free end of the arm and a slider holds the drive motor.

In this way, the full width of the rectangular extrusion plate is respected due to the axial movement of the extrusion plate as well as the transverse movement relative to the extrusion axis;
A square extrusion plate can also be lubricated using a circular lubricant rotated by a drive motor.

In another embodiment of the invention, an arm pivotable towards the extrusion axis is freely oriented towards the extrusion line for automatic lubrication of a rotatable extrusion mandrel that can run from an extrusion ram of a direct extruder for pipes. The weaving section is configured in a U-shape, the U-shaped part is oriented toward the extrusion axis with its opening, and at least two lubricants are provided inside the U-shaped part, respectively, in the cylinder of the extrusion mandrel. It is arranged in a receiving device supported via a guide mechanism extending towards the surface.

With this, the entire circumferential surface of the extrusion mandrel is lubricated by simultaneously rotating and moving the extrusion mandrel using a phantom lubricant that can be moved in the radial direction with respect to the extrusion axis using a U-shaped arm with a free end. can be done.
